dmesg of regular boot + startx

Trying to run Arch Linux on a Lenovo Y400 with an nvidia GT750M graphics card.
When trying to boot the nouveau drivers consistently spit out multiple errors.
Computer continues the boot process. Errors also occur whenever I try to run
anything with hardware acceleration, such as Xorg. It is a similar output to
the one that occurs during boot: PBUS, PIBUS, and PGRAPH errors. Attached is a
dmesg log of a regular boot and startx.

Also a log of opening up Xorg: http://pastebin.com/w48Dx4qq
And a log of opening up weston: http://pastebin.com/1VPFgapP

Did this work with older kernels? If so, a bisect would be useful. Most reports
of pgraph timeouts are on GK104/GK106 chips while you have a GK107...

I had errors in 3.16 as well. I'm not sure if the errors are related. I was
getting different errors during boot. Here's a few dmesg logs from that kernel.

Unresponsive but numlock key works: http://pastebin.com/kzbWdZ0W

Boots with multiple errors: http://pastebin.com/yRxvh5bB
